Foreign Language Exchanges and boarding schools

If you run an exchange with a school abroad and teach in a boarding school, could you please leave me a message here or PM me? I'm currently looking at options for our own exchange and wondering what other schools do. We have very few spare beds so are thinking about accommodating our boarders' partners with day pupils instead, which will be quite tricky to organise, but currently looks like the best option as far as getting as many participants as possible goes.
Do you use temporary beds e.g. camp beds for visiting pupils? Do they stay in dorms with current pupils or have their own accommodation? Do the accompanying teachers also stay in school?
Thank you for your help!

As I recall, we farmed everything out to parents of day pupils (including overseas staff). Many were happy to put up at least two exchangees each.
The most important thing to remember is the risk (or accusation) of serious child protection issues if you accommodate unchecked foreigners in a boarding house.
